【摘要】 以准噶尔盆地整体构造演化特征为背景,并根据盆地各区构造演化和含油气方面的差异性,在分析了历次构造单元划分方案和有关的地质综合报告、地震剖面的基础上,提出了一套盆地与区带研究都适用的、统一的、规范的构造单元划分方案。该方案将盆地划分为6个一级构造单元和44个二级构造单元,与以往方案的差别主要体现在:北天山山前冲断带单独划分为一级构造单元;五彩湾凹陷归入东部隆起;中拐凸起归入西部隆起;对陆梁隆起、原昌吉凹陷、原帐北断褶带进行了细划分。更多还原

【Abstract】 Based on the whole structural evolution in Junggar basin, considering the differences in the structural evolution and petroliferous nature in each area, this paper analyzes the all classification conceptions for the structural units and relevant comprehensive geologic reports and seismic profiles, and proposes a set of new and regular concept suitable for classification of the basin and regional structural units. The concept includes 6 Class-Ⅰ units and 44 Class-Ⅱ units. In comparison with previous concepts, the piedmont thrust belt in north Tianshan mountain is classified as unit of Class-Ⅰ; Wucaiwan sag classified into the uplift in eastern Junggar basin; Zhongguai swell into the uplift in western the basin; Luliang uplift, Changji sag and Zhangbei fault-fold zone are sub-classified in this article.更多还原
